2020-04-27bnxt_en: Reduce BNXT_MSIX_VEC_MAX value to supported CQs per PF.Vasundhara Volam1-1/+1
Broadcom adapters support only maximum of 512 CQs per PF. If user sets MSIx vectors more than supported CQs, firmware is setting incorrect value for msix_vec_per_pf_max parameter. Fix it by reducing the BNXT_MSIX_VEC_MAX value to 512, even though the maximum # of MSIx vectors supported by adapter are 1280.

2020-04-27bnxt_en: Fix VF anti-spoof filter setup.Michael Chan2-9/+2
Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1. In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched. So we now set or clear the anti- spoof setting directly without retrieving the old settings in the stored vf->func_flags which are no longer valid. We also remove the unneeded vf->func_flags.

2020-04-26net: hns3: optimize the filter table entries handling when resettingJian Shen8-105/+94
Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

2020-04-26net: hns3: use mutex vport_lock instead of mutex umv_lockJian Shen2-13/+19
Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

2020-04-26net: hns3: refactor the promisc mode settingJian Shen8-46/+122
As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here.

2020-04-26net: hns3: refactor the MAC address configureJian Shen6-218/+860
Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.

Now CPTS HW time reading code is implemented in timecounter->cyclecounter .read() callback and performs following operations: timecounter_read() ->cc.read() -> cpts_systim_read() - request current CPTS HW time CPTS_TS_PUSH.TS_PUSH = 1 - poll CPTS FIFO for CPTS_EV_PUSH event with current HW timestamp This approach need to be changed for the future switch to PTP PHC .gettimex64() callback, which require to separate requesting current CPTS HW time and processing CPTS FIFO. And for the follow up patch, which improves .adjfreq() implementation. This patch moves code accessing CPTS HW out of timecounter code as following: - convert HW timestamp of every CPTS event to PTP time (us) and store it as part struct cpts_event; - add CPTS context field to store current CPTS HW time (counter) value and update it on CPTS_EV_PUSH reception; - move code accessing CPTS HW out of timecounter code and use current CPTS HW time (counter) from CPTS context instead; - ensure timecounter->cycle_last is updated on CPTS_EV_PUSH reception. After this change CPTS timecounter will only perform timekeeper role without actually accessing CPTS HW.

2020-04-23net/mlx4_en: use napi_complete_done() in TX completionEric Dumazet3-13/+13
In order to benefit from the new napi_defer_hard_irqs feature, we need to use napi_complete_done() variant in this driver. RX path is already using it, this patch implements TX completion side. mlx4_en_process_tx_cq() now returns the amount of retired packets, instead of a boolean, so that mlx4_en_poll_tx_cq() can pass this value to napi_complete_done().

2020-04-23cxgb4: fix adapter crash due to wrong MC sizeVishal Kulkarni1-7/+20
In the absence of MC1, the size calculation function cudbg_mem_region_size() was returing wrong MC size and resulted in adapter crash. This patch adds new argument to cudbg_mem_region_size() which will have actual size and returns error to caller in the absence of MC1.

2020-04-23qede: Add support for handling the pcie errors.Sudarsana Reddy Kalluru2-1/+68
The error recovery is handled by management firmware (MFW) with the help of qed/qede drivers. Upon detecting the errors, driver informs MFW about this event which in turn starts a recovery process. MFW sends ERROR_RECOVERY notification to the driver which performs the required cleanup/recovery from the driver side.
